In the middle of a spacious classroom, a chalkboard filled with polished wooden planks and microscopes sits. A group of students sit at the desk, chatting and laughing, while a classroom lamp casts a warm glow on the desks. A cup of steaming coffee fills a nearby desk, labeled with a spreadsheet explaining the complex theories of scientific experimentation. The air is thick with the scent of freshly brewed coffee and cold beer.
